ENVR

Bit 0: Voltage reference buffer mode enable This bit is used to enable the voltage reference buffer mode..

HIZ

Bit 1: High impedance mode This bit controls the analog switch to connect or not the VREF+ pin. Refer to Table196: VREF buffer modes for the mode descriptions depending on ENVR bit configuration..

VRR

Bit 3: Voltage reference buffer ready.

VRS

Bits 4-6: Voltage reference scale These bits select the value generated by the voltage reference buffer. Other: Reserved.

CCR

VREFBUF calibration control register

Offset: 0x4, reset: 0x00000000, access: read-write

0/1 fields covered.

TRIM

Bits 0-5: Trimming code These bits are automatically initialized after reset with the trimming value stored in the Flash memory during the production test. Writing into these bits allows to tune the internal reference buffer voltage..
